Biology Undergraduate Course Prerequisites/Restrictions

Students are expected to complete all prerequisites and meet all course restrictions prior to enrolling in any undergraduate biology course at UC San Diego. Prerequisites and restrictions are enforced in all courses. Please see the PDF link below for the most current prerequisite/restriction information.

  • Prerequisites are courses which must be completed prior to enrollment in the subsequent course to ensure adequate preparation.
  • Restrictions are enrollment limitations put upon a course. Most commonly courses are restricted to certain class levels (junior/senior only, for example) or to certain majors.

The prerequisites for the following courses will NOT be waived, regardless of circumstance. There are no exceptions.

  • BILD 1, 2 and 3

How to request a prerequisite/restriction waiver

  1. Submit a prerequisite/restriction waiver request via the UC San Diego Course Pre-Authorization System. *Student User ID/PID and Password/PAC required*
  2. A submission confirmation email will be sent to the student's @ucsd.edu account.
  3. Once a final decision is made on the prerequisite waiver request, an email will be sent to the student's @ucsd.edu account.

Important Notes

  • If the prerequisite/restriction waiver request is approved, it is the student's responsibility to add (or waitlist, if full) the course via WebReg. All standard add/drop deadlines apply.
  • Final decision time will vary and is dependent on instructor response time.
  • System availability coincides with the release of the Schedule of Classes for the given quarter and is available until 4:00pm on Friday of the second week of classes.

Transfer Credit

Students who have transferred course work to UC San Diego from another institution may have earned the course equivalency necessary to satisfy course prerequisites.

Transferring from a California Community College

Course(s) must be completed, transferred to UCSD, and appear on the student's UCSD Academic History. If the UCSD equivalent, as noted on ASSIST, does not appear on the student's Academic History, the student should contact Biological Sciences via the Virtual Advising Center for further direction.

Transferring from Non-California Community College/Four-Year Institutions

Course(s) must be completed, transferred to UCSD, and appear on the student's Academic History. If an established UCSD equivalency exists, it will post on the student's UCSD Academic History. If there is no UCSD equivalent listed, the student should contact Biological Sciences via the Virtual Advising Center for further direction. A petition may be required. Please note petitions are not guaranteed to be approved.

Please be aware that UC transferability does NOT imply that a transfer course is equivalent to a specific course offered at UC San Diego.

UCSD Graduate Students

Students with graduate standing may have prerequisites/restrictions waived for any undergraduate Biology course. Graduate students should utilize the UC San Diego Course Pre-Authorization System to request such waivers.

Visiting/Non-UCSD students

Individuals with visiting student status who are taking course(s) at UC San Diego (e.g. in Summer Session, via an exchange program, student-employee program, etc.) may have prerequisites/restrictions waived for any undergraduate Biology course. Visiting students should utilize the UC San Diego Course Pre-Authorization System to request such waivers.

Note: Students enrolling via UCSD Extension's Concurrent Enrollment program or the Cross Enrollment program should NOT use the UC San Diego Course Pre-Authorization System. Enrollment is processed via the respective paper form/card.
